A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.

The study examined what NHL-teams should improve. This has been done by studying the significant statistics of NHL-seasons, and with linear regression identifying what NHL-teams should do to win many points and thereby get a good placement in the final table. The most interesting result of the study is that the statistics on faceoffs and shots on goal and power play efficiency most seasons where irrelevant for the outcome of a season..

Conect AB wants to know how they can use ITIL in their organization. Right now their company is in an expansive phase and needs a more structured way to work. They have been thinking of improving their way of work for several years but haven?t had the time to do so. Now they have realized they need to work more efficiently to able to grow further.

This study concerns how organizations manage various problematic areaswhen implementeing Business Intelligence and experiences from BusinessIntelligence project failures on management level. In order to highlightthese questions, we have carried out interviews with four organizationswhich have great experience in working with Business Intelligence on adaily basis.The result of the study shows that all organizations deal with difficultiesregarding cost-benefit issues and justification concerning BusinessIntelligence investments. The result also showed that the organizationsfaced difficulties with integration concerning time and cost. Documentingand securing support systems presented different attitudes between theorganizations, primary in the question about sub complements to BusinessIntelligence and in the way that they were documented. In the discourse oflegal issues and privacy the majority of the organizations chose not to storepersonal information relative to legal security demands.

The thesis work has been carried out at Volvo Aero Corporation (VAC) in Trollhättan. VAC has entered a partnership as developing and producing partner with engine manufacturer Pratt & Whitney and is currently at the starting phase of producing the turbine rear frame (TEC) to the engine PW1000.The purpose of this study was to create a report on process level that describes the conditions and the potential with PW1000 TEC to reach the product cost calculation taking into account lead times and describe alternative method solutions.The report describes a comparison between the present flow (2012), a flow based on product cost calculation (2016) and a potential flow (2016). The work has mainly been based on acquiring the knowledge and information available to inspect the present flow; this has been done by workshop observations, meetings and gathering of the information that is available on the work site for the PW1000 TEC.The information obtained has been merged into an Excel document, called Roadmap. It serves as a roadmap with current situation as the start and the potential flow for 2016 as the goal. With the roadmap as a tool, assumptions have been taken considering the flow and how it will change, where processes have been eliminated, reduced or marked as a problem..

This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.

The residential and service sector in Sweden accounts for approximately 38% of the total energy usage and Sweden has an aim to reduce the total energy use by 20% by 2020 compared to 2008, which means residential sector will have to improve energy efficiency. As part of that a law was instituted by the Swedish parliament that all properties must have an Energy Performance Certificate (EPC) to thereby give the property owners a greater insight into energy use in their buildings and propose recommendations for energy-efficiency measures. On the EPC, a value on the building's energy performance in terms of energy use in kWh / m2 per year is declared, of which electricity is a share of it. Instructions on what to include in the amount facility electricity for running the facilities is regulated by the authority for building, Boverket while SVEBY has made an interpretation of the regulations in their report "Brukarindata bostäder" where they have a table on what should be included in the amount and what not to include.This report is a study of two similar apartment buildings, where one of the buildings recently underwent renovation, to see if the declared amount of energy for electricity, in the EPC, is consistent with the measured value, and whether there has been any reduction in facility electricity in the renovated building after the renovation.The result shows that the measured value of the building electricity was 2.6 kWh / m2 per year, 28,8 %, lower than the declared value in the building that have not undergone a renovation. Calculation of values from previous years (2011) by the same percentage of facility electricity as in the results of the measurements, 56.7%, it becomes clear that the declared value for facility electricity in the EPC of the renovated building do not correspond with reality and that there has been an increase in use of facility electricity after the renovation..

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Den bostadspolitik som förts de senaste två decennierna har gett oss en alltmer segregerad stadskärna i Stockholm. Byggsubventionernas avveckling på 90-talet har lett till en historiskt låg byggtakt och ett byggande som ensidigt riktat sig till resursstarka grupper i samhället.Parallellt med detta har stora delar av hyresbeståndet ombildats till bostadsrätter vilket medfört att många relativt billiga hyreslägenheter i äldre fastigheter har försvunnit ur beståndet. Dessa är svåra att ersätta med nyproduktion, då dessa är dyrare.Kärnproblemet är förstås att det är dyrt att bygga hus och om man antar att den nuvarande bostadspolitiken består är det ytterst angeläget att utveckla kostnadseffektiva byggmetoder för att möjliggöra lägenheter med överkomliga hyror som kan bidra till att motverka boendesegregationen på sikt.Vårt förslag består av ett bostadshus i Stadshagen. Fastigheten är indelad i två byggnadskroppar som länkas samman via ett system av loftgångar kopplade till ett trapphus. Husen är uppbyggda av volymelement som staplats på en platsgjuten sockel.

Environmental management officers ? leadership and employeeship in local environmental health authorityThe purpose of this study was to illustrate the working situation of municipal environmental health management officers. This is a qualitative study where I have interviewed ten environmental officers in ten municipalities in Sweden. The interviews were based on a half structured interview guide with questions. I have interpreted the interviews through different leadership theories.

Swedish healthcare are in need of radical changes to meet the requirements from both the government and the patients to create organisational working methods that better support the patients through their healthcare processes. Digitalization of patient data has been going on for decades in order to increase participation and understanding among patients in their care processes. However, availability of information does not ensure understanding. Therefore, resources should be devoted to create conditions to enable participation. The purpose of this study is to explore how visualization of patient data in the patient?s journal can affect the consultation in the encounter between the doctor and the patient.

During the early 1990´s, the Swedish commercial air traffic was de-regulated and the new market-condition made it possible for low-budget airlines to enter the Swedish market. The former monopolistic airline company, Scandinavian Airline Systems (SAS), was facing a new type of competition which had the advantage of offering much cheaper air trips than SAS. Adding the decrease of profitability that struck SAS as well as other airline companies after the terrorist attacks on the 11th of September, forced them to carry out a mayor reorganization programme. The programme, called ?Turn Around 2005?, was a direct economical measure that begun in 2002 and lasted until 2005 and resulted in a cost saving of 14,5 billion SEK as well as a notice or a transfer of 6000 employees.The purpose of this essay is to investigate if the opinion of the consumer, the image, corresponds with the profile that SAS wishes to mediate today.

Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.
